Brought a complete genuine ambient lighting kit for my a4 saloon. red, white and door handle light. the red and white light for the door works fine but i cannot get the door handle light to work on either of the 4 doors. can't seem to see an option in C.E.M and can't access the door modules. i have two audi a4 b7 and neither want to connect to the door module via vcds. any help?
